+title: Apache Kudu Weekly Update November 15th, 2016
+author: David Alves
+---
+Welcome to the twenty-third edition of the Kudu Weekly Update. This weekly blog post
+covers ongoing development and news in the Apache Kudu project.
+
+<!--more-->
+
+## Project news
+
+* The first release candidate for Kudu 1.1.0 is [now available](http://mail-archives.apache.org/mod_mbox/kudu-dev/201611.mbox/%3CCADY20s7ZKZkPmUEcTexW%3D%2B_%2BLnDY2hABZg0-UZD3jvWAs9-pog%40mail.gmail.com%3E).
+
+  Noteworthy new features/improvements:
+  * The Python client has been brought to feature parity with the C++ and Java clients.
+  * IN LIST predicates.
+  * Java client now features client-side tracing.
+  * Kudu now publishes jar files for Spark 2.0 compiled with Scala 2.11.
+  * Kudu's Raft implementation now features pre-elections. In our tests this has greatly
+    improved stability.
+
+  Community developers and users are encouraged to download the source
+  tarball and vote on the release.
+
+  For more information on what's new, check out the
+  [release notes](https://github.com/apache/kudu/blob/branch-1.1.x/docs/release_notes.adoc).
+  *Note:* some links from these in-progress release notes will not be live until the
+  release itself is published.
+
+* On November 7th, the Kudu PMC announced that Jordan Birdsell, from State Farm, had been
voted
+  in as a new committer and PMC member.
+
+  Jordan's contributions include extensive work on the python client, throwing it some much
needed
+  love, and bringing it to feature parity with the other clients.
+
+  Besides his extensive code contributions Jordan has also been active in reviewing other
+  developer's patches and helping the community in general, on slack and other channels.
+
+  Jordan has been doing great work and the Kudu PMC was pleased to recognize his contributions
+  with committership.
+
+* Mike Percy will be presenting Kudu Wednesday 16th November at [Apache Big Data Europe,
in Seville](https://apachebigdataeu2016.sched.org/).
+
+* Congratulations to Haijie Hong for his [first contribution to Kudu!](https://gerrit.cloudera.org/#/c/4822/).
+  Haijie fixed some edge cases in BitWriter that were blocking RLE usage for 64 bit types.
+
+* Congratulations to Maxim Smyatkin for his [first contributions to Kudu!](https://gerrit.cloudera.org/#/q/Maxim).
+  Maxim has contributed several patches helping with debug and cleanup.
+
+## Development discussions and code in progress
+
+* A lot of progress has been done towards the goals that were set in the scope docs introduced
in
+  the last couple of posts. Specifically:
+
+  * Dan Burkert, Todd Lipcon and Alexey Serbin have doubled down on the security effort.
They have
+    been working on enabling Kerberos authentication and rpc encryption. The [security scope
doc](https://docs.google.com/document/d/1cPNDTpVkIUo676RlszpTF1gHZ8l0TdbB7zFBAuOuYUw/edit#heading=h.gsibhnd5dyem)
+    has been updated with the latest plans for security and many patches have been merged
already.
+
+  * David Alves has continued the work on [consistency](https://s.apache.org/7VCo). Up for
review
+    and partially pushed is a patch series to address row history loss if a row is deleted
and then
+    re-inserted. Also in progress is work to make sure that scans at a snapshot from followers
+    always return same data as if they were executed on the leader. This helps with Read-Your-Writes
+    when reading from lagging replicas.
+
+  * Adar Dembo has been making good progress [addressing issues seen with the LogBlockManager](https://s.apache.org/uOOt).
+    A series of patches have been merged with various fixes to block managers in general
and to the
+    log block manager in particular.
+
+  * Dinesh Bhat has been working on improving the manual recovery tools for Kudu. Namely,
he has
+    added a tool to force a remote replica copy to a destination server, and a tool to delete
a
+    local replica of a tablet. The latter is useful when a tablet cannot come up due to bad
state.
+
+  * Jean-Daniel Cryans has implemented RPC tracing for the java client, greatly improving
+    debuggability. JD also has added ReplicaSelection to the java client, allowing to perform
+    scans on replicas other than the leader, which should be of great help for load-balancing.
+
+  * Besides the feature parity contributions, Jordan Birdsell has laid out a
+    [roadmap for Python client work](http://mail-archives.apache.org/mod_mbox/kudu-dev/201611.mbox/%3CCAGaaj_VKfB4mhu6eExHCWo0%3D6Qd0HFWy7bg9e39JgOaFPGJ1nQ%40mail.gmail.com%3E)
+    for the 1.2 release. Feedback from other Python client users is certainly appreciated.
